328 T. D. A. COCKERELL. 



Macroglossstpis rubricata Sm. 9. 



Peculiar for the reddish abdomen, clouded with darker; except 

 for the broader abdomen it rather suggests a Ligurian honey bee. 



Y I NOi.l.OSS I Smith. 

 Xenoglossa fulva Sm. 9 (T.). 



Superficially just like X. patricia Ckll. ; ground (tegumentary) 

 color of head black, and of abdomen fulvous, as in patricia. It 

 diners from patricia by having the pygidial plate broader at apex ; 

 the abdomen larger and with appressed fulvous pubescence covering 

 the surface, in consequence of which it looks paler and duller than 

 that of patricia ; thoracic pubescence a redder orange. 



Xenoglossa mustelina (Centris mustelina Fox) is a valid species, 

 not a synonym of X.fulva. 



MELISSODES Latr. 

 Melissodes haemorrhoidalis Sm. 



South America. Looks like a small Tetralonia gabbi, having the 

 same reddish abdomen, black basally. It has the hair of the meso- 

 thorax black. 



Melissoues smithii D. T. {californicus Sm.). 



A large species like M. obliqua, with the same red hair on inner 

 side of first joint of hind tarsi in 9 • The female has the thorax 

 densely covered with bright fulvo ferruginous hair ; abdomen with 

 very distinct light hair-bands, hair of apex black ; wings hardly so 

 dark as in obliqua. In obliqua the first r. n. joins the second s. m. 

 a considerable distance from its end, in smithii almost at its end. In 

 obliqua the flagellum is strongly reddened beneath, which is not the 

 case in smithii. The male smithii has the hair on the apical part of 

 ventral surface of abdomen black, but otherwise pale; abdomen 

 above with very distinct bands, like the 9 ; flagellum wholly dark, 

 or at any rate not distinctly reddened. 



Melissotles hii-siita Sm. % (T.). 



Flagellum red beneath. Ordinary looking species, with yellow 

 clypeus; black labrura ; no yellow spot on mandibles; hair of thorax 

 above very lively fulvo-ferruginous Close to M. aurigenia, but 

 wings faintly dusky, with dark brown stigma and nervures, not 

 whitish, with ferruginous stigma and nervures as in aurigenia. The 

 labrum of aurigenia is yellow, but that of hirsuta is black.
